Description

Trying to make a Variable Editor on the incident table read-only does not work with the setVariablesReadOnly method.

Steps to reproduce:

1. Create an onLoad client script on the Incident table with g_form.setVariablesReadOnly as true
2. Open the Incident form that has the variable editor
3. Notice the variables in Variable editor on Incident are still editable

Release or Environment

Kingston, London, Madrid

Cause

The setVariablesReadOnly method is specifically reserved for the sc_task and the sc_req_item table.  Will not work with any other table

Resolution

To set the Variable Editor to read only a different table like incident, please follow these steps:

1. Create a Client Script on the Incident table
2. Paste the following script:
   

   function onLoad() { 
   $("variable_map").querySelectorAll("item").forEach(function(item){
   var variable = item.getAttribute("qname"); 
   g_form.setReadOnly("variables."+ variable, true); 
   }); 
   }

3. This will require to uncheck (set to false) the "isolate script" checkbox (This checkbox is not on the form by default) Steps below how to bring it to the form)
   1. To do that right click in the header -> Configure -> Form Layout
   2. On the left side find "Isolate script" and bring it to the right and save
4. Save changes
   This should make the Variable Editor on the incident table read-only

Hi @karan15 ,

Ideally Variables don't have the option to make read only.

You have to create an onload client , 

Also check the: 

 Applies on Requested Items

Now in the script section, add the below piece of code:

function onLoad() {

         g_form.setReadOnly('YOUR VARIABLE NAME', true);

}

Note: If you have made the variable as mandatory from the variable level then you would not be able to make it read only. Before making read only you have to make the variable as non mandatory then make it read only, using below code:

function onLoad() {

         g_form.setMandatory('YOUR VARIABLE NAME', false);

         g_form.setReadOnly('YOUR VARIABLE NAME', true);

}
